Selective vagotomy
- Selective vagotomy involves division of the vagal trunks distal to the hepatic and celiac branches, thereby preserving vagal innervation to the gallbladder and celiac plexus.
- This reduces the incidence of gallbladder dysmotility, gallstones, and diarrhea. However, selective vagotomy also results in complete gastric vagotomy, necessitating a drainage procedure.
- Selective vagotomy is not the operation of choice, as it is needlessly complex and not superior to truncal vagotomy; it is rarely used and only of historic importance.
